      I know you can solve this problem in JS. The whole point is the problem *should not exist*. Python has no problem sorting an untyped array according to natural sort order, instead of somehow defaulting to string coercion, which is almost never what you want.

      there is no 'natural' sort order for heterogeneous untyped collections. what sort order is 'natural' for [1, '10', null, false, NaN, [], {}] array? i don't want to rely on 'magic' detecting 'right' sort type and prefer consistent method behavior regardless of the data

      There *is* a natural sort order for *homogeneous* untyped collections. Heterogeneous untyped collections should raise an error (something which Python 2 didn't do and Python 3 fixed). Coercing to strings by default is batshit insane.

      The only reasonable implementation of untyped array sort is to *do what the comparison operators do*. That's what all versions of Python do (Py3 just doesn't allow comparing disparate types, Py2 does). Javascript does not. That makes *no* sense.

      "Do what the comparison operators do" doesn't make sense when the comparison operators aren't transitive. a < b && b < c doesn't imply a < c in JS.

      They damn well better be when the operands are the same basic type (except NaN, but blame IEEE for that one), which would make this behavior do the logical and intended thing by default.

          you can safely use typed arrays you can use .sort((a,b) => +b - +a) and pray that all will be numbers but no, you prefer to complain about language
